TurnKey Fileserver script seems broken

[MrNonoss]

Hi lads,

I try to get the TurnKey Fileserver installed on my Proxmox 8.2.7 without success.

When I enter the command, it allows me to select the TurnKey appliance I wish, then select a location for template then container, and finally ends with an error: 1@212 Unknown failure occured.

When ran in debugging mode using -x, I get the following details:

+ pct create 110 local:vztmpl/debian-12-turnkey-fileserver_18.0-1_amd64.tar.gz -features keyctl=1,nesting=1 -hostname turnkey-fileserver -tags proxmox-helper-scripts -onboot 1 -cores 2 -memory 2048 -password DKkGixh55Wg= -net0 name=eth0,bridge=vmbr0,ip=dhcp -unprivileged 1 -rootfs vm_storage:8

Removing completely the function to get the local IP solved the issue, but I'm not sure it is intended to work this way

# Get container IP
set +euo pipefail # Turn off error checking
max_attempts=5
attempt=1
IP=""
while [[ $attempt -le $max_attempts ]]; do
  IP=$(pct exec $CTID ip a show dev eth0 | grep -oP 'inet \K[^/]+')
  if [[ -n $IP ]]; then
    break
  else
    warn "Attempt $attempt: IP address not found. Pausing for 5 seconds..."
    sleep 5
    ((attempt++))
  fi
done
